We offer a range of precious and non-precious Heraeus manufactured fine bonding ribbons. These ribbons are available in gold, silver, platinum and copper, other materials are available upon request.
Gold bonding ribbons are specifically engineered for high reliability in many applications, including microwave devices and high frequency applications. They take advantage of the “skin effect”, when using high frequency signals, most of the flow is on the surface.
Exacting manufacturing specifications produce bonding ribbons that have a homogeneous composition, stable mechanical properties, smooth surfaces and consistent widths, insuring a minimizing of snagging in bonding.
The ribbons we supply start life as 99.99% pure aluminium. Doping with carefully controlled additives allows for high purity, while production ribbons that exhibit precise dimensions, exacting mechanical characteristics and looping behaviour.
